' To all whom itmiay concern:

'tion.

Be it known that I, CLARENCE EMERsoN PosToN, a citizen of the United States,residing at Crawfordsville, in the county of Montgomery and State of Indiana, have invented a new and useful Improvement in Brick-Machines, of which the following is a specifica This invention and has for its object to provide means for giving to the bricks produced by the machine unique and novel faces and ends as distinuished from known smooth or glazed faces.

ough-surfacing is desirable for a variety of reasons, amon appearance an a better bond when laid, and this invention provides means for producing. it without hand-labor and the use ofbrooms or other devices heretofore employed for that purpose. x v

The device herein disclosed embodies the use of wires ap lied to the mouth or delivery- 0 ening of a rick-machine which delivers t erefrom a continuous bar or strip of clay, which is taken to the cutting-table to be cut into bricks of esiredv size. I These wires roughen the sides orsurface of the bar, sothat when the bricks are finally cut and fired the desirable rough surface is oduced as distinguished from the smoot surface which would otherwise result. j I

A further feature of my invention is the 'use of scrapers which scrape off and cast aside the strips cut by the wiresfrom the sides of the bar, which form the ends of the finished bricks. I

A further feature of this invention is a wire provided with disks attached nearth'e topof. the mouthpiece to loosen and cut into fragments or make ragged the top of the bar to 'repare the bricks with rough faces and ends.

he top of the bar makes the face of the brick in this case, and a plain wire would not do, because it wouldshave off the waste, but not break it, and-it would lie up and cover the roughened surface, inasmuch as there is no practicable way of sweeping or cleaning the waste off of the top of a barof clay. The wire. with disks cuts the waste and breaks it into fragments, giving the desired surface effect, and also small enough so that when a roller is subsequently passed over the surface relates to brick-machines,

which are more ornamental the fragments unite with the bar and form a good bond, still showing the rough surface.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the mouthpiece of a brick-machine provided with the improvement. Fig. 2 is a horizontal section thereof. Fi 3 is a erspective of a modification in wlnch the isk-wire is omitted and a middle plain wire is used to divide the bar, forming two rough-surface bricks in each length; and Fig. 4, a-'detai l of wire, showing square plates set at a right angle. Fi s. 5, 6, and 7 'are'detail perspective views 0 the several parts-detached.

Referring'specifically to the drawings, 6 indicates the mouth iece of the brick-machine.

;This has near t e sides thereof vertical wires 7, which shave off thin strips from the edges of the bar of clay as it issues from the month. These wires are strainedoverthe rim of the mouthpiece andsecured at the ends by means of. hooks 8, roject ing from plates 9, attached to the wa s of the mouthpiece bymeans of screws 10. The screws a're and as. the wires stretch the screws are tightened to take up the slack.

At 11 are indicated scra ers, which consist of metal strips .secure at their upper ends to thetop of the mouthpiece and depend in line with the wires 7, being twisted to present their edges to the cut produced by the wires and to throw off to the sides the waste strips out off by the wires.

In the form shown in Fig. 1 a top wire 12 is used, fastened at the ends by means of screwhooks 17, secured to brackets 18, attached to the outside of the mouthpiece, and these wires carry disks 13 of thin metal, set slantingly or at an angle tothe line of motion of the bar, and the inclination of the alternate disks is, reversed. Thewire is so positioned that the disks cut into or score the top of the bar. To prevent sag of this wire, inasmuch as the strain is great, it is-supported at the middle by a screw'14, having which holds the wire, the screw being held by a plate 15,'attached to the top of the mouthpiece. Instead of being set round and slantingly the disks may be square and at right angle to the wire, as shown in Fig. 4,

eft loose when the wires are first attached,

a notch in the end,

' the appended claims and large or small, as desired, all depending on the plasticity or resistance of the clay. v

The form shown in Fig. 3 is used for thin bricks to divide the barin half. A horizontal wire 16 is placed across the middle of the mouth and secured at'the ends by the same means. I The wire producesthe rough sur,

face, and during the subsequent operations the upper and lower halves remain together and are handled as one brick until after fir ing,t when they are separated.

will be understood-that after the bar is cut in the manner indicated it is cut vertically and transversely into bricks on an ordi-- nary cuttin -table. The face and also the ends of the rick are rough-surfaced by the means indicated. .The scrapers llvprevent the shavings or strips adhering to and being carried along with the bar, which would obstruct other parts of the machinery and prove generally inconvenient, and effectively dispose of the waste. Y

It will be understood that my invention I Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1'. The combination with the mouthpiece of a brick-machine, of Wires stretched across the same, at the sides thereof, for shaving strips from the bar, and scrapers beyond the wires, adapted to cast off the shavings so produced. a 2. The combination with the mouthpiece of a brick-machine, delivering a bar. of material, of a wire stretched across the same, adj acent t0 the surface of the bar, and having thereon cutting devices adapted to cut into the surface of the bar.

' 3. The combination with the mouthpiece f of a brick-machine, delivering a bar of material, of a wire stretcheda'cross the same, adjacent to the edge of the mouth, and having thereon disks arranged at an angle to the line of motion of the bar and adapted tobreak the surface of said bar.

4. The combination with the mouthpiece of a brick-machine, delivering a bar of material, of means to shave strips from the surfaces of the bar, and scrapers beyond said means, arranged to cast off the said strips from the bar.'
